Equalizing Indoor Air Pressure:
A Crucial Balancing Act
It is important not to neglect the impact of an unbalanced ventilation system. If an air exchange unit does not expel and intake equal amounts of air, a negative or positive air pressure imbalance occurs.
HRV - Heat Recovery Ventilator
Ideal for colder climates
In colder climates, where home heating is essential, the heat recovery ventilator (HRV) is the proper choice. The HRV keeps the home supplied with a steady flow of fresh outdoor air. As stale, warm air is expelled, the heat recovery core warms the incoming fresh, colder air before it is distributed throughout the home. The result is a constant supply of fresh air, no unpleasant drafts and greater home comfort. In addition to heat recovery and improved air quality, the HRV provides necessary ventilation while controlling excess humidity.
ERV - Energy Recovery Ventilator
Ideal for warmer climates and high-humidity environments
Even though the energy recovery ventilator (ERV) is suitable for colder climates, it is usually associated with warmer climate homes where humidity control is important. The ERV recovers heat (like the HRV); however, it also recuperates the energy trapped in moisture, which greatly improves the overall recovery efficiency.
The ERV process is as follows:
In humid climates and air conditioned homes, when it is more humid outside than inside, the ERV limits the amount of moisture coming into your home. In dry climates and humidified homes, when the humidity level is reversed, the ERV limits the amount of moisture expelled from your home.
